For this reason, we especially emphasise scientific approaches for harmonising chronologies for sophisticated and robust proxy data integration.In this respect, up-to-date age modelling techniques are presented as well as tools for linking records by age equivalence including tephrochronology, cosmogenic 10Be and palaeomagnetic variations. Elbrus, Caucasus Mountains derived from a snow pit and a shallow ﬁrn core is presented for the 2009–2012 period. Elbrus, Caucasus Mountains derived from a snow pit and a shallow ﬁrn core is presented for the 2009–2012 period.Finally, to avoid inadequate documentation of chronologies and assure reliable correlation of proxy time series, this paper provides recommendations for minimum standards of uncertainty and age datum reporting.

A combination of isotopic analysis, SEVIRI red-greenblue composite imagery, MODIS atmospheric optical depth ﬁelds derived using the Deep Blue algorithm, air mass trajectories derived using the HYSPLIT model and analyses of meteorological data enabled identiﬁcation of dust source regions with high temporal (hours) and spatial (ca. Seventeen dust deposition events were detected; fourteen occurred in March–June, one in February and two in October.
Paleoclimatology, Second Edition, is an essential textbook for advanced undergraduate and postgraduate students studying climatology, paleoclimatology and paleooceanography worldwide, as well as a valuable reference for lecturers and researchers, appealing to archaeologists and scientists interested in environmental change.This resource contains reference materials on the radiocarbon dating method.Beginning with a summarization of the method, descriptions of three principal means of measuring residual carbon14 (14C) activity follow, including gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry (AMS).Thirteen events originated in the Middle East, in the Syrian Desert and northern Mesopotamia, from a mixture of natural and anthropogenic sources.Paleoclimatology relies on a number of geologic concepts, including the idea that sediment layers are deposited chronologically, with the oldest layers occurring at the bottom, and uniformitarianism, that the present is the key to the past.
We concentrate on the time interval of focus for the INTIMATE (Integrating Ice core, MArine and TErrestrial records) community (60e8 ka).
